What should I include in the letter?

Provide taxpayer name, TIN, affected tax years, explanation for delinquency, proposed corrective steps, and attach supporting documents such as payment receipts or draft returns.

Can I sign electronically?

Who do I send the letter to?

Send to the payer, issuer of the informational return, or the tax authority contact listed on any IRS notice; keep proof of delivery and record the date sent.

What a Letter Regarding Delinquent Tax Returns Is

A Letter Regarding Delinquent Tax Returns is a formal written notice sent by a taxpayer, preparer, or authorized representative to a payer, client, or tax authority explaining that one or more required federal or state tax returns were not filed on schedule. It states the tax years affected, reasons for delinquency, proposed corrective actions (filing dates, payments, or installment plans), and lists supporting documents. The letter creates a clear record of the taxpayer’s acknowledgement and intent to resolve outstanding filing obligations and can accompany restored filings, Forms 1040, 1099 corrections, or responses to formal IRS notices.

Why this Letter Matters for Resolving Outstanding Returns

A clear, factual letter documents intent to comply, helps coordinate corrected filings or withheld payments, and supports mitigation of penalties. It provides a single reference for the taxpayer, preparer, payer, and tax agency during follow-up.

Who Typically Prepares or Receives This Letter

Several parties use this letter to explain and correct late filings and to document remediation steps before tax authorities escalate enforcement.

Individual taxpayers and small business owners communicating past-due returns and proposed cure actions.
Tax professionals (CPAs, enrolled agents) documenting client remediation and giving the payer required tax forms.
Payors and employers responding to requests for corrected payor information or reporting adjustments.

Use the version that matches whether you are notifying a payer, responding to an IRS notice, or sending corrected informational returns.

Signatory Roles and Authority

Taxpayer

Common Mistakes to Avoid When Preparing the Letter

Using an incorrect TIN or mismatched name, which can trigger backup withholding and delay processing by payers and the IRS.
Failing to list exact tax years and return types; vague descriptions complicate reconciliation and slow resolution with tax authorities.
